This clasp is often called a hidden clasp
because when the watch band is closed the only portions of the clasp that show
are the buttons. Because of this “invisible” clasp, the butterfly clasp is a
very popular watch band clasp. Butterfly clasps are great for metal watch bands.
The clasp is attached to the band by a tube with pins on each side of the band.
The push buttons add an extra level of security to this watch band because the
clasp cannot open until the buttons have been pushed in. To determine the size
clasp that you need, you measure the tube length.
